I thought I'd offer this to the spitlist so it can find a good home.
Manifold - ported and polished - I think there could be more work done
to it especially in the splitter area but it is nice work - not done by
me
the cross over is not blocked
This manifold is for the 4 port head.
Carb details:
CC needles - these will be quite rich (stock needles were either BO or
DD's, relative richness of a BO/DD is 20% at full throttle a CC is 42%)
- if you don't want them I'll keep them and use them as the rich needle
for the new setup)
new .090 jets - I don't know if I like them they use a rubber hose
between the bowl and the jet - but seem ok
thinned thorttle shafts that are rivetted and soldered in place - shafts
were new 4 race weekends ago - I don't really like how the solder turned
out
all burrs removed from the flow path
no modifications to the bridge
new bronze bushings for the shafts
new needle and seat - not grose jets
standard float covers
Heat shield that extends above and below the carbs - it isn't pretty but
it works - there is a crack (well about 2 or 3" long maybe longer) at
the bend on the rear side -- but still works well
phenolic spacers are .25" thick or so and matched to the manifold.
2" velocity stacks made of spun aluminium with full radii on the ends,
these have some scuffs on them
No air cleaners - Winners Circle sells some filter socks that will work
with these.
linkage details -
linkage for the choke operation is there - the bar between the two carbs
- I never used it...just kept it rather than loosing the 6 ounces.
linkage for throttle cable is there - I don't think it is the correct
setup but I will put an old throttle cable on to show how it was working
when on the race car - it could be better. Bar between the two carbs is
there but it needs 2 new throttle return springs
if the needles weren't so rich I'd say that it is a bolt on and go type
deal...but as always (I were buying) I would go through them yourself to
make sure everything is how you want it, if I wasn't switching to the
1.5" setup I would have just bolted them back onto the car and run them.
Also, this isn't a concourse set, there are scuffs and dings from the
constant disassembly/assembly that occurs with a race car no matter how
careful you are. I only used these for the past 2 years and before that
they sat on this car in a storage shed since 1985.
